Twitter clamps down on cryptocurrency scams

SAN FRANCISCO - Twitter is taking measures to prevent cryptocurrency-related accounts from running scams on its platform, the company said on Wednesday.

"We're aware of this form of manipulation and are proactively implementing a number of signals to prevent these types of accounts from engaging with others in a deceptive manner," Twitter said in a statement.

Last week, Twitter sought help from users to improve the quality of conversations on its platform to address rising criticism against social media companies for failing to protect users from online abuse and political manipulation.
